Thank you for contacting us, As we checked your site data we found out that you are using two AMP plugins AMP and AMP for WP, we will recommend keeping only AMP plugin active.
The AMP site scan feature shows you plugins and themes that are not compatible with AMP.
The AMP plugin removes those invalidations (errors) to create a valid AMP page but it keeps a record in the validation tool, those errors are the errors that are added by other plugins and themes, the validation tool will help plugin and theme developers to find the AMP validation issue in their plugin it also helps users to understand the validation issues.
If you are a non-developer, You can disable the validation tool from AMP settings using AMP->Other->Toggle off “Enable Developer Tools”
In case you just started using the AMP plugin, we will recommend checking our Getting Started guide also feel free to check the video series for the AMP plugin.
